When I worked at Hughes Aircraft I used to visit the
Hughes Helicopters operation in the next building. They used
a combination of very new and very old production equipment and
tools. They had a hydro-forming setup which used a spark discharge
in the water to form the pressure. Never saw the inside of the
power supply for the thing, b ut it was a cube about six feet on
the side, so it could have held a lot of pretty big capacitors.
The thing must have used a relay of some kind to hook the charged
capacitors to the spark gap, as there was a big flash and loud
sound from the inside of the PS when they fired the sparks.
Reminds me of the dangerous capacitor experiments stuff on
Bill Beaty's web, contributed by a respected member of this
group!
